I use it for about 1 month with JBL jrx115,
trs trs complment good bass to be just "a box is sick" strong and powerful yet powerful to less than 400 nothing to say,
Thomann communication is excellent store trssrieux,
the box has a long view if the card electronic rsiste ... fawn all the housing is guaranteed for 3 years.
single point ngatif ouafff weight is really heavy!

--- Rglage volume knob
--- The button SETTING THE frquence
--- Between XLR
--- Start button stop

I would do the same happy choice.
Purchase confident.
